Symptom
- The inclusion of non-stock, non-pricing text components in the Bill of Materials (BOM) is required.
- The BOM item category "Text Item (T)" seems suitable, but these items do not appear in sales orders.
- This results in the error: "No item category for component (T184: )".
This issue occurs when the Sales BOM includes a component without a valid item category being determined during BOM explosion.
Environment
SAP S/4HANA Cloud Public Edition
Reproducing the Issue
- Create a Sales BOM with a text item or placeholder component.
- Use item category group T or leave component material blank.
- Attempt to create a sales order with the BOM header.
- Error appears: “No item category for component (T184: )”
Cause
In SAP S/4HANA Public Cloud, Sales BOM components must reference valid material masters with appropriate item category group and configuration.
- Text items (Item Category “T”) without a material number are not supported for BOM explosion in sales orders.
- Public Cloud does not support adding lines without a material (unlike in On-Premise with free text components).
Resolution
Two Workarounds available:
Option 1: Use Dummy Material as Text Line
Create a non-stock, non-valuated dummy material to behave like a memo line.
- In the Material Master:
- Material Type = NLAG (Non-Stock Item)
- Item Category Group = NLAG or similar non-valuated group
- In the BOM:
- Add the dummy material as a component.
- Fill the “Component Description” field to reflect the purpose (e.g., notes).
- Item Category Determination:
- Ensure that the item category TAX is used, with:
- Pricing = X (Not Relevant for Pricing)
- Billing Relevance = A (Not Relevant for Billing)
- Ensure that the item category TAX is used, with:
This avoids any pricing (e.g., 0.01 JPY issues) or posting.
Option 2: Maintain Texts at Sales Order Level
If the text is purely informational and does not need to be in the BOM:
- Use the Texts tab in the sales order header or item.
- Configure Output Management to include these texts in the printed forms.
- Avoids using materials or components entirely.
Important Notes
- Item category TAXN is not recommended, as it allows pricing (B), leading to residual charges (e.g., 0.01 JPY).
- Use TAX with Pricing = X to fully suppress pricing.
- Item category determination in Public Cloud is influenced by higher-level item categories (like TAP in LUMF BOMs) and may ignore custom entries that don’t match SAP-delivered logic.
